Question

Transform each polar equation an equation in rectangular coordinates identify its shape.
1) rsin(theta)=3 (I just need the shape)
2) r = 2cos(theta) (I just need the coordinates)
3) r = (4/(2cos(theta) - 3sin(theta))) (I just need the coordinates)
4) rcsc(theta) = 5 (I just need the shape)

Answer 2

I can't use the draw function !

Answer 3

Ok, then can you help me with the coordinates then?

Answer 4

What do you mean by "needing the coordinates"? You have to convert from one coordinate \(\textbf{system}\) to another.

Answer 5

Exactly...

Answer 6

Doesn't the rectangular coordinate system look like regular coordinates? Ex: (x, y)

Answer 7

Yes, rectangular refers to the coordinate grid. The polar coordinate system describes the same points in a different way.

Answer 8

Specifically, points in the rectangular coordinate system taking the form \((x,y)\) are expressed in the form \((r,\theta)\) in polar coordinates, where \(x=r\cos\theta\) and \(y=r\sin \theta\).

Answer 9

I thought y was theta not rsin(theta)
